Most energy released is radiated by the solar chromosphere\, g iving rise to bright\, highly structured '\;footpoints'\; and  7\;ribbons'\; of chromospheric emission. The big picture of a solar fl are\, and the significance of flare ribbons in the global reconnection sce nario\, is well established\, but high-resolution observations show fine s patial\, temporal and spectral structure which can be probed to further ex plore flare physics. In this talk I will overview the basic framework of a solar flare and its development in the solar chromosphere\, highlighting some examples of how fine scales are being used to investigate energy rele ase and transport. I will focus on results from the IRIS spacecraft in the UV\, and a newly-opened window on flares in the mid-infrared.\n LOCATION:Maria Margaretha Kirch Haus Konferenzraum END:VEVENT END:VCALENDAR
